SPECIFICATION forming part of Letters Patent No. 551,367, dated December17, 1895.

Application tiled Januaryk 9, 1895. Serial No. 534,286. (No model.)

To Z-Z whom t may concern:

Be it known that I, GEORGE F. CREMER, of St. Paul, Ramsey county,Minnesota, have invented certain Improvements in lVater-Bicycles, ofwhich the following is a specification.

My invention relates to improvements in marine velocipedes, its objectbeing to provide an improved consti-notion thereof and simple,easily-operated means for steering and propelling the same.

To this end my invention consists in providing a pair of similar hullsor shells arranged parallel With each other and having a bicycle-framesecured intermediate thereof. The vessel is driven by means of ascrew-propeller operatively connected with the footpedals by means ofsuitable gearing, and each hull is preferably provided with a rudder,which is connected with and actuated by the handle-bar. The cross-barsconnecting the two hulls or shells and supporting the frame andpropelling connections are provided with means for adjustmentlongitudinally of the shells and also for the adjustment of the hullstoward and from each other. The propellershaft is supported by means ofverticallyadjustable hangers depending from the crossbars, the hangersbeing preferably provided with ball-bearings, in which the shaft turns.The propeller-shaft is also adapted to be adj usted longitudinally tocompensate for different-sized gearing.

My invention further consists in the improved features of constructionhereinafter more particularly described, and pointed out in the claims.

In the accompanying drawi1igs,for1ning part of this specification,Figure i is a side elevation of my machine. Fig. 2 is a top elevationillustrating the steering and propelling attachments and the adjustableconnections between the hulls and cross-bars. Fig. 3 is a cross-sectionof the same, taken on line o: :c of Fig. 2. Fig. 4 is a seetionaldetailof one of the rear bearings for the propeller-shaft, and Fig. 5 is asimilar view of the forward bearing. Fig. 6 is a detail of the hangerfor supporting the rear bearing for the propellershaft. Fig. '7 is adetail f the bevel-gear, sprocket and pinion at the front of themachine, by which power is transmitted to the propeller.

Fig. S is a plan view of the supporting-plate for the gear and sprocket,secured to the under side of the front cross-bar. Fig. 9 is a detail ofone of the end bearings for the driving-shaft. Fig. l0 is a longitudinalsection of the handle-bar standard, the Linner inclosing tube beingbroken away to show the inclosed bar, and Fig. Il is a detail of one ofthe clamps for securing the tube upon the bar.

In the drawings, A represents the bicycleframe provided with thenecessary seat, handle-bar, pedals, cbc. This frame is supported uponthe cross-bars and i3, which connect the hulls 4 and 5. These hulls arepreferably of the form shown in the drawings and are shown lled Withair-tight cans, so that in case of puncture the ext-ire hull will notbecome illed with Water. Secured to the tops of the hulls are the platesG, provided with longitudinal slots 7, passing through which slots andsimilar slots S in the cross-bars 2, 3 and 9 are bolts l() to providefor the adjustment of the cross-bars longitudially of the hulls and forthe adjustment of the hulls toward and from each other.

Running from the sprocket ll upon the pedal-shaft l2 of the frame A tothe sprocket 13, mounted upon the driving-shaft 14, is thesprocket-chain I5. The shaft la is journaled in ball-bearings 1G in thedoWnWardly-depending lugs 17 of the plate IS, the plate 1S being securedto the under side of the cross-bar 2 and projecting rearwardly from thesame, forming support for the rod 19 of the bicycleframe. Meshing withthe bevel-gear 20, also mounted upon the driving-shaft, is the pinion2l, connected with the screw 22 at the rear of the machine by means ofthe shaft 23. The propeller-shaft 23 is supported in the ballbearings2i, 25 and 26, the bearing 24C being supported by means of the hanger27, connected to the plate 18, and the bearings 25 and 26 beingsimilarly supported from the cross-bars 3 and 9 by the hangers 28 and29. The hanger 27, as shown in Fig. '7, passes through the slot G3 inthe rearwardly-extending arm (Si of the plate I8, and is connected uponthe opposite side of the slot to the' rod 19 of the bicycle-frame. Thisrod i9 is provided witli a turnbuckle 65, 'by which its length may bevaried in the adjustment of the parts.

IOC

rtherewith.

collar 4l, formed by the bottom of the hanger In the bearing 25 r(seeFig.. 4) the propellershaft is inclosed bythe tube 30, preferably brazedthereto. The end pieces 31 and 32 of the bearing and the inner block33'iit closely to the tube 30 and turn with it in the rotation of theshaft. i Between the block 33 and the collar 34 are placed the balls 35of the bearing. The collar 34 is pivotally connected to the hanger 29,projecting downward from the crosssbar. The different parts yofthe'bearing are held in contact by means of the lug 3G'upon one end ofthe tube engaging one end of the bearing and the nut 37 screw-threadedIn the bearing 24 (see I `ig.5) the end pieces f 3S and 39 are securedto the shaft and revolve The inner collar 40fand the outer 27, remainstationary in the turning of the shaft and the other parts ofthe bearingbean against them. The balls 42 of the bearing lare placed between thefixed and turning parts. The pinionv 21 and the collar 43 separating thepinion from the bearing are also secured to the shaft rby means of thespline 44. VThe different parts ofthe bearing and the pinion are held incontact by means of the nut 45, screw-tineaded rupon the shaft andengaging one end of the bearing, and the nut 4G also screw-threaded uponthe shaftV and abutting against y,the pinion. The shaft is made in twopieces, the part 47, carrying the bearing and pinion, fitting into thebody of the shaft so as to be easily removed therefrom for the purposeof removing the bearing.

f -In Fig. 9 is shown a det-ail of one of the bearings 16 for thedriving-shaft I4.' In this Aform of bearing the parts 43 and 49 and theencircling collar formed by the end of the lug I7 remain stationary, andthe shaft revolves therein upon the balls 50, traveling in the groove51.

The handle-bar standard of the bicycle-.

frame extends down through the cross-bar 2 and has secured to its lowerend the crosspiece 53. The ends of this cross-piece are connected withthe tillers 54 of the rudders 55 by means of the ropes or wires 56 insuch manner that they can both be operated simultaneously by the turningof the handle-bar.

I show in Fig. l0 an improved form of handle-bar standard for use withmy machine. In this form the standard is made in two sections 57 and 58,fitting closelyinto the ends of the tube 59, which in turn is adapted toturn inside the hollow sleeve or case 60 upon the interposedball-bearings 6l. The ends of the tube 59 are slitted, so that they willgive, and are clamped upon the ends of the standards by means of theclamps 62. The clamps 62 also hold the tube 59 from vertical movement inthe sleeve 60. Vith this form of standard the bar turns freely in theouter sleeve, and either section ,of the bar can be independentlyadjusted by the loosening of the clamp.

IVhile I show in the drawings and prefer to use a steering-rudder hingedto the rear of each of the hulls, it is evident that this arrangementcan be modifiedand one rudder instead be placed intermediate of the rearof the hulls.

Secured to the'tops of the hulls are the footrests 63 to be used inmounting to prevent breaking through the tops of the hulls.

yBy means of the adjustable connections between the cross-bars and thehulls the bars rmay be adjusted longitudinally of the hulls and thehulls adjusted toward and from each other at will. The propeller alsomay be raisedfand lowered by means of the nuts 64 upon the ends of thehangers supporting the propeller-shaft.

It will be evident that on. account of the adj ustability of the forwardhanger inthe slot 63 and of the cross-bars connecting the hulls,

which serve as longitudinally-'adjustable sup-y ports for the other twohangers, the propellershaft can be adjusted longitudinally to compensatefor different-sizedl gearing upon the counter-shaft when differentrelative speed is desired.
